I always thought they should be replaced whenever the spark plug is changed.

...then find any paperwork that you may have on when they were last replaced. I use 50k -80k miles as my reminder unless your car is throwing codes about coil issues. Factors such as high heat due to living in hot areas, track driving, and long highway commutes in start and stop traffic may tend to lessen the coil's life so think about your driving conditions in addition to the visual inspection as another variable for when you think that you may need new coils. I've got 85k miles on my M3 but it is stored in a heated and air-conditioned garage, no track days, no burnouts, no doughnuts, no launches and the majority of its miles are long interstate commutes with no start and stop traffic (I am lucky that I don't live in a densely populated area of the USA).
